Another huge jump in weekly wage earning—though not nearly as impressive at 107.3 percent—happened in Douglas county in Colorado, a suburb outside of Denver. Though no big tech company IPOs happened at the end of last quarter, the area does have some big name companies in growth industries like healthcare and telecommunications.

But hey, maybe the newly civic minded CEOs, with Zuckerberg leading the pack, will decide to do something about it now?
